[Class 37] An electric condenser comprises a ceramic tube 1 carrying a fixed electrode 2 which co-operates with an adju stable electrode 5 carried on a rod 6 having screw-threaded engagement with a unit 8 in the form of a coil of wire which closely embraces the end of the ceramic tube 1 and has a free end 9 for electrical connection. The element is dipped in a solder bath to solidify coil 8, the rod 6 being treated to prevent adhesion of the solder. A supporting member 10 surrounds nut 8 to which it is soldered, and carries an arm 12 having a claw-like end for engaging the screw-thread on rod 6 to give good electrical connection. A second connection member 3 surrounds the fixed electrode 2 to which it is soldered. In a modification, the fixed electrode is formed of a coil of wire surrounding the tube 1.

Abstract: 515,800. Valve amplifying circuits. BAIRD TELEVISION, Ltd., and MAITLAND, C. E. June 13, 1938, No. 17508. [Class 40 (v)] An intervalve coupling arrangement for very high frequencies comprises the inductance 2 of a tuned circuit and a resistance 3 connected between the anode of the first valve 1 and the high-tension source, the junction of the elements 2, 3 being connected through a lowreactance condenser 4 and an inductance 5 to earth, and the junction of elements 4, 5 being connected through an inductance 6 to the grid of the second valve 7. The inductances 2, 6 may be tuned by the inherent inter-electrode capacities 8, 9 of the valves 1, 7, respectively. Damping resistances may be added in series or shunt to the tuned circuits 2, 6 and the inductance 5 to give a wide pass-band of uniform response.

[Class 66] [Also in Group XXXVI] A sealed container 20 for an electrical component comprises a flexible non-metallic wall part 21 which permits volume variation of an impregnant and is bonded to a metal part 22 to which a further metal part is soldered after assembly with the component, to complete the enclosure. The end-cap 15 is soldered on.

Abstract: 566,703. Variable condensers. MULLARD RADIO VALVE CO., Ltd., and MAITLAND, C. E. July 1, 1943, No. 10714. [Class 37] A plate of a variable condenser has a series of frangible members around its edge to permit of exact capacity matching. In the example, a series of holes 3 and narrower slots 5 give rise to lines of incipient fracture 4, at which small parts 6 may be broken off.
